SPECIFICATION forming part of Letters Patent No. 362,916, lated May l0, 1887.

Application filed February Il, 1887.

To @ZZ whom, it may concern:

Be it known that I, GEORGE W. ZEIG LER, a citizen of the United States, residing at fashington, in the District of Columbia, have invented certain new and useful Improvements in Portable and Adjustable Tables or Desks; and I do hereby declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which it appertains to make and use the same.

rIhis invention relates to certain new and useful improven'ients in portable and adjustabletables or desks; anditeonsists,substantially, in the parts as constructed and in such pecu-v liar arrangement and combinations of parts as will hereinafter` be more particularly described, and pointed ont in the claims.

The invention has for its object to provide a table or desk which shall be capable of ready adjustment to anyinclination desired, and 'be thereby securely maintained or held.

Further, the invention has for its object to supply a table or desk which can be taken entirely apart for portability or shipment; and, finally, the invention has such other objects in view as will more fully appear from t-he description hereinafter following, when taken in connection with the accompanying sheets ofdrawings, wherein Figure l represents a side View of a table or desk embodying the principle of my invention, and Fig. 2 is a longitudinal sectional elevation thereof on the line x x. Fig. 3 is a detail view, partly in section, to more clearly indicate the construction of the socket which holds the beam and the legs or supports for the table or desk. Fig. 3a is a transverse sectional view of Fig. 2 on the line y y, showing the table-top or desk as being inclined or brought to an adjusted position. Fig. 4 is a top plan View of my invention with the top of the table or desk removed. Fig. 5 represents in perspective a View of one of the side plates for effecting the adjustment of the table-top or desk. Fig. 6 is a top or plan view of one of the leg and beam sockets. Fig. 7 is a view in detail ofthe binding cam or eccentric, and Fig. Sis a view in detail showing the manner of constructing the ends of the cross-beam for fitting within the notches of the side adjust- Serial No, 226,443. (No model ing-plates and for the reception of the ribs of the sockets in which it is held.

Before proceeding with a more full description I desire to state that I am aware that tables or desks have been heretofore invented havinglike objects as the present; but the construction and arrangement ot' parts of all former inventions of the kind with which I am conversant is thought to be substantially different from suoli as are herein resorted to.

Reference being had to the several parts by the letters marked thereon, A represents the adjustable top ot' the table or desk, and B B the supporting-legs therefor. These support- 'ing-legs are brought togethetl at their upper ends and held by a malleable-iron clamp, C, having sockets c c for their reception. rlhc Sockets a a are united by a rib, b, and intermediate thereof tlie clamp is formed with two upright portions, c c, having their opposite edges preferably slightly beveled, and forming between them a vertical recess or cavity, d, designed lfor the reception of the end of the beam which unites or connects the two pairs of legs or supports. Projecting outward from the bottom of the recess ol' each clamp C is a pin, c, that forms the pivotal snpport for the adjusting-plates D, and which also acts as an auxiliary to the operation of the bindilig cam or eccentric, hereinafter referred to.

rlhe adjusting-plates D at each end of the table or top are nunierously. perforated, as

shown, for the purpose of lightness, and they are each formed with inwardly-extendingcogs or teethf, arranged in the aic of a circle, and forming between them wedge-shaped notches .for the reception of the correspondinglyshaped tooth g formed in each end of the cross-beam E. rI he said plates I) are formed with perforated ledges h, designed to support and hold the top of the table or desk by thev shaped and are pivoted to the outer sides of the plates D, and they are for the purpose of being moved around and tightened upon the pins e of the clamps C in such manner that when the top A has been adjusted to the position desired it may be drawn down tightly in place upon the beam E. Stops n are formed therewith, which rest against the stops j when the said cams are loose.

The beam E remains stationary in practice, and is formed at opposite sides near each end with grooves 7c, which receive the two vertical portions ot' the clamp G,and is thereby held in place.

To one side ofthe top A, at each end, I have provided curved arms or supports H, having their upper extremities hooked or notched,

as at Z, and they support between them pivotally a set of drawers, I, having secured to each end of their case a pintle or lug, m, received by or into the notches Z. It is obvious that at whatever position the table maybe adjusted these drawers will always seek or maintain their proper position, due to the manner of their support.

The operation of my invention is as follows: The pairs of legs having been forced into their sockets, they are arranged the proper distance apart, and the beam E is then forced down into the cavity or recess d, with the upright portions c c of the clamps iitting tightly in the grooves k k thereof. The top A is then placed down over the beam in such manner as that the K slots i of the ad j listing-plates D will pass down over the pins e, projecting outwardly from the leg-clamps. Ifitis desirable to have the top in a perfectly-horizontal position the central wedgeshaped notches, f, ofthe plates D are made to t over the corresponding teeth, g, formed at the ends of the beam E. If, however, an inclination of the top A is desired, it is simply necessary to lift it free ot' the teeth g and bring the plates D around to the notches f thereof that correspond to the position sought. When the proper adjustment is had, and for the purpose of-securing the top A tightly to its position, by turning the eccentric cams around in thedirection indicated by the arrow they will draw upon the pins e, and thus tightly bind the plates D upon the beam. At whatever position the top of the table or desk is brought the drawers I will always conform thereto and maintain their proper position.

In an application tiled of even date here-l with, Serial No. 226,442, I have set forth and claimed the construction of the clamps for the reception of the supporting-legs of the desk or table, together with the manner of forming the clamps by which to adapt them for the reception of the connecting-beam; hence it will be Vunderstood that I lay no claim herein to such means of plates D, having notches fitting the teeth of said beam, substantially as shown and described.

2. In a portable table or desk, the combination, with the supporting-legs, of the clamps C. constructed of the sockets a a, connectingrib b, and vertical portionsc c, having their opposite edges beveled and forming a central cavity or recess, substantially as described 3. In a portable table or desk, the combination, with the supporting-legs andthe clamps uniting the same, having pins e, of the beam fitting between the clamps, having a tooth at each end, the adj Listing-plates formed with notches arranged in the arc of a circle to fit these teeth and having slots z' tting upon the pins of the clamps, substantially as described.

4. In a portable table or desk, the combination, with the clamps C, having pins c, and the adj Listing-plates and top, of theeccentrio cams G, pivoted to the outer sides of the plates and surroundingk the pins e, the same adapted to be turned to bind against said pins, substantially as and for the purpose described.

In testimony whereof I affix my signature in presence of two witnesses.

GEORGE w. ZEIGLER.
